What is X3F?

Sigma Raw (X3F) contains raw sensor data from Sigma cameras using the unique Foveon X3 sensor technology.

What is PPM?

Portable PixMap (PPM) is a simple color image format that stores RGB pixel data in ASCII or binary representation.

When Should You Use X3F vs PPM?

Use X3F When...

Reach for X3F when your priority is sigma/foveon camera raw processing — its uncompromising quality ensures every detail is preserved.

Use PPM When...

Reach for PPM when your priority is simple color image processing, academic use — its uncompromising quality ensures every detail is preserved.

X3F vs PPM: Key Differences

  • •The core technical difference: X3F relies on lossless compression whereas PPM uses lossless compression.
  • •Neither format changes compression philosophy — both are lossless compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
  • •Alpha channel support: PPM lacks transparency support.
  • •File sizes: X3F files typically range 25-60MB per photo and PPM files Larger than JPEG, smaller than BMP for same data.
  • •X3F is optimized for sigma/foveon camera raw processing while PPM is designed for simple color image processing, academic use — choose based on your specific workflow needs

Advantages of X3F

  • ✓The lossless nature of X3F means file sizes stay reasonable while handling Sigma/Foveon camera raw processing efficiently.
  • ✓From mobile devices to enterprise servers, X3F is recognized and supported everywhere.
  • ✓The trade-off for X3F's perfection is larger files — but for archival work, it is worth every megabyte.
  • ✓X3F is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Advantages of PPM

  • ✓PPM uses lossless compression tailored for Simple color image processing, academic use.
  • ✓PPM is supported natively on virtually every device, browser, and operating system.
  • ✓PPM files are bit-for-bit perfect, preserving every pixel and sample for professional work.
  • ✓PPM integrates seamlessly with all major creative tools and workflows.

Troubleshooting X3F to PPM Conversion

  • !PPM shows visible compression artifacts → lower the compression level or switch to a lossless variant
  • !The converted PPM image looks washed out → the source X3F likely uses a wider color space than PPM supports
  • !PPM file is much larger than expected → check if the conversion preserved an unnecessarily high resolution
  • !Text in the converted PPM looks fuzzy → text-heavy images benefit from higher quality settings or a different output format
